The Kalman Evolve: Closing the Gap in Kalman Filtering via Interpretable Algorithm Discovery

Researchers introduce Kalman Evolve, a framework that uses large language models to discover improved filtering algorithms for state estimation by optimizing both noise parameters and the update structure of classical Kalman filters. The approach addresses performance gaps in nonlinear sensing scenarios like Doppler radar and LiDAR, achieving up to 12% RMSE improvement over standard methods.

Online Causal Kalman Filtering for Stable and Effective Policy Optimization

Researchers propose Online Causal Kalman Filtering for Policy Optimization (KPO) to address high-variance instability in reinforcement learning for large language models. The method uses Kalman filtering to smooth token-level importance sampling ratios, preventing training collapse and achieving superior results on math reasoning tasks.

High-Resolution Range Profile Classifiers Require Aspect-Angle Awareness

Researchers demonstrate that High-Resolution Range Profile (HRRP) classifiers achieve significantly better accuracy when incorporating aspect-angle information, showing 7% average improvement and up to 10% gains. The study proves that estimated angles via Kalman filtering can preserve most benefits, making the approach viable for real-world radar and signal processing applications.

Joint Estimation of Sea State and Vessel Parameters Using a Mass-Spring-Damper Equivalence Model

Researchers developed a new method for real-time sea state estimation that jointly estimates both sea conditions and vessel parameters without requiring prior knowledge of wave-vessel transfer functions. The approach uses a mass-spring-damper model with advanced filtering techniques to achieve performance matching traditional methods that assume complete transfer function knowledge.
